The problem
Fashion-commerce recommendations usually optimise for another purchase without understanding what the customer already owns.
South African legal information is scattered across portals with limited keyword search, while international e-discovery platforms are often priced beyond the local market.
An Android app that drives picking and packing for warehouse and fulfilment operations.
What was built
Fashionly grounds recommendations in the user's wardrobe, builds outfits from existing items and recommends products only where a genuine wardrobe gap exists. Khanya, a LangGraph stylist with about 15 typed tools, handles wardrobe access, catalogue search, saved looks and human-stylist bookings.
An integrated research, e-discovery and learning platform: hybrid semantic search across more than 10,000 judgments, a precedent citation graph, structured document extraction, AI-assisted discovery and stateful research workflows.
